ASH REMOVING AND RECEIVING DEVICE Filed Aug. 24, 1942 w. A mm W w 6 iJaZ Patented Oct. 24, 1944 UNlTED STATES P ten? OFFICE 2 Claims.

This invention relates to ash receiving and removing devices forfurnaces.

An object of this invention is to provide a metallic pit formingstructure for mounting below a furnace in which a dolly is adapted to bemounted, the dolly being constructed to receive which may be embedded inthe ground below the furnace.

A further object of this invention is to provide a structure of thiskind which includes an ash guiding means for guiding the dropping ashesinto a collector or receiver which is mounted on a removable dolly.

A further objectof this invention is to provide a structure of this kindwhich may be mounted beneath the present construction of a furnace so asto facilitate the removal of ashes.

A further object of this invention is to provide a structure of thiskind which may be used with either manually fed or mechanically fedfurnaces and which will eliminate the creation of dust around thefurnace during the removal of the ashes, as is at present the case.

It is known that devices of this kind have been produced which providefor pulling of the dolly and ash receiver from the pit coincident withthe raising of the trap door, but such devices have the disadvantage ofnot permitting the use of the dolly in transferring the receiver to apoint remote from the furnace. With a construction of this kind, thedolly and receiver may be shifted to any desired remote point, and thereceiver lifted from the dolly and then returned to the pit with anempty receiver, thus making it unnecessary for the user of thisstructure to immediately remove the ashes from the receiver.

In the drawing:

Figure 1 is a detail top plan of an ash removing structure constructedaccording to an embodiment ofthis invention,

Figure 2 is a sectional view taken on the line 2-2 of Figure 1, and

Figure 3 is a top plan partly broken away of the ash receiver dolly.

Figure 4 is a sectional view taken on the line 4-4 of Figure 3.

Referring to the drawing, the numeral IO designates generally a furnaceof conventional construction which is provided with an ash pit |3 in thelower portion thereof. A pit forming structure generally designated asll is adapted to be disposed below the furnace IO with a portion thereofprojecting either forwardly or laterally of the furnace, and the pitforming structure is adapted to be embedded in the ground and extendedbelow the floor |2 upon which the furnace IO is adapted to rest.

The pit forming structure I includes a bottom wall Ill which is formedof a horizontally disposed rear part IS and an obtusely disposedupwardly and outwardly extending forward part |6. A vertically disposedrear wal1 I'l extends upwardly from the rear end of the rear part |5 andVertivcally disposed side walls |8 extend upwardly from the bottom wallM and the side walls l8 are secured to the opposite Vertical edges ofthe rear wall I'l. The forward part IS of the bottom wall |4 is formedwith a fiange or horizontally disposed upper end portion |9 which may beembedded 'in the floor 12, adjacent the upper surface of the 'fioor.

A top wall Zii is mounted on the upper edges of the pit forming memberII and is provided with an opening 2| forming an entrance or exit for adolly to be hereinafter described. The side walls |8 may be formed withhorizontally disposed and laterally extending flanges 22 which areadapted to be embedded or secured in the fioor |2 and the top wall orplate 20 is adapted to rest or be secured to theflanges 22 and |9. Adoor or closure 23 is hingedly secured as at 24 to the top wall 20 andis formed adjacent the forward portion thereof with a detent ordepression 25 within which a U-shaped handle 26 is adapted to engage.The handle 22 is loosely mounted through the plate or closure 23 and isadapted to be lifted upwardly to an operative position and to the limitprovided by means of stop members 21 which are secured to the oppositelegs of the U-shaped handle 26 below the plate or closure 23.

The plate or top wall 20 at a point below the ash pit 3 of the furnacev|0 is formed with a downwardly tapering ash guiding member, generallydesignated as 28. The ash guiding member 28 includes oppositely disposedside flanges 29 and 30 which are disposed in downwardly convergentrelation and forward and rear fianges 3| and 32 which are also disposedin downwardly convergent relation and secured' at the opposite endsthereof to the fianges 29 and 30.

A dolly generally designated as 33 is adapted to be removably disposedin the :pit forming structure II and includes a frame structure formedof a pair of rearwardly divergent arms 34 and 35 and a forwardlyextending arm 36 which extends forwardly from the convergent ends of thearms 34 and 35. Each of the arms .34 and 35 as shown in Figure 2includes an upwardly offset rear portion 31 connected to the centralportion of the arm by means of a vertically disposed connecting member38. A depending wheel bearing w member 39 is secured to the lower sideof each of the 'pair of arms 34 and 35 and a wheel 40 is rotatablycarried by the 'bearing member 39.

The forward arm 36 is formed with an upwardly offset forward portion 4|connected to the main portion of the arm 36 by means of a Verticallydisposed connecting member 42. A front Wheel bearing 43' is rotatablymounted about a Vertical axis below the offset portion 4| and has awheel 44 rotatably secured thereto. The bearing 43 includes an upwardlyextending shaft 45 which extends through the offset portion 41, and aU-shaped handle mounting member 46 is secured to the upper end of thestub shaft 45. An elongated handle 41 is pivotally secured at its rearend as at 48 between the flanges or arms of the bearing 46 and theforward end of the handle 41 may be provided with a hand grip member 49.The hand grip member 49 is adapted to be positioned closely adjacent theupper end portion of the forward part Hi of the bottom wall l4 When thedolly 33 is positioned within the pit H.

The Vertical connecting members 38 and 42 with the main portions of thearms 34, 35 and 36 form a seat portion on which an ash receiver 53 isadapted to removably engage. The ash receiver 50 when' in receivingposition is adapted to be disposed directly below the guide member 28 sothat the ashes shaken down from the grates of the furnace HI will dropthrough the guide member 28 and into the receiver 50. In the useand'operation of this structure, the pit or pit forming member H isadapted to be embedded in the ground and secured within the floor |2 sothat the horizontal wall 15 will be ,positioned below the ash pit l3 ofthe furnace [0. The dolly 38 with the receiver 53 mounted thereon isthen positioned within the lower portion of the pit I l. The door orclosure 23 will be normally closed so that the dust raised by thedropping of the ashes from the furnace into the receiver 53 will notrise into the body of the cellar. V

When it is desired to remove the receiver 5B,

1: the door or closure 23 is raised to the dotted line position shown inFigure 2. The hand grip 49 may then be gripped and the dolly 33 may thenbe pulled upwardly along the upwardly extending bottom wall part 16which constitutes the runway for the pit. The receiver 50 may then bemoved while positioned on the dolly 33 to any desired remote positionwith respect to the furnace I 0 and then lifted off of the dolly 33. Inthe event the user of this device employs additional receivers 5B, thefilled receiver may be placed in a desired location for collection andthe empty receiver then placed on the dolly 33, whereu'pon the lattermay be returned to the pit H and the door or closure 23 closed.

The ash removing structure hereinbefore described is of simpleconstruction so that it may be manufactured and sold at small cost andwhen in use will provide a structure which will eliminate in great partthe generation of dust from the ashes within the body of the cellar orthe room within which the furnace IO is located.

What I claim is:

1. A wheeled truck comprising a frame formed `of a pair of rearwardlydivergent arms and a forwardly extending arm extending from theconvergent ends of said pair of arms, each arm including an innerhorizontal member, a Vertical extension at the outer end of eachhorizontal member, and an outer horizontal member, parallel wheelbearings carried by the rear pair of said outer members, Wheelsrotatably carried by said bearings, an inverted U -shaped front wheelbearing, a stub shaft carried by said front bearing journalled throughthe front outer member, a U-shaped member secured to said stub shaft onthe upper` side of said front outer member, the bight of said U-shapedmember rotatably engaging said upper side and holding said stub shaftagainst downward movement, an elongated handle, and means rockablysecuring said handle between the arms of said U-shaped member.

2. A wheeled truck as set forth in claim 1 wherein said inner horizontalmembers are substantially longer than said outer members to thereby forma downwardly offset article seat, said Vertical extensions providingmeans to hold the article against lateral movement.
